Spiced Apple Cider Jelly Shots

Directions

1. Pour apple cider into a large saucepan and sprinkle gelatin over top; let stand, without stirring, until gelatin softens, about 5 minutes. Whisk in sugar. Heat and stir over low heat until sugar and gelatin are completely dissolved, 8-10 minutes (do not boil); remove from heat. Stir in vodka; pour mixture into a 9-in. square baking pan coated with cooking spray. Refrigerate, uncovered, until mixture is firm, about 2 hours.
2. To unmold, run a sharp knife along edges of gelatin; invert onto a cutting board and lift off pan. Cut into 64 squares; brush tops with bitters and sprinkle with cinnamon sugar. If desired, garnish with apple slices.
